  • Patent number: 7859503
    Abstract: In driving a liquid crystal display device having an alignment regulating structure for regulating liquid crystal, when the display state of the pixel is to be changed from a dark display to a bright display, a difference between the magnitude of a voltage Vd4 applied to the liquid crystal of the pixel at the beginning of the first frame and the magnitude of a voltage Vd3 applied to the liquid crystal of the pixel in the second frame or a subsequent frame, is set to be greater than a voltage Vod that decreases in the first frame due to an increase in the liquid crystal capacitance of the pixel.

  • Patent number: 7154467
    Abstract: A control circuit of a liquid crystal display device has a display driving data generation section. The display driving data generation section includes a conversion table 46 for storing compensation data corresponding to the combination of the significant bits of the image data nFi of the current frame and of the post driving status data (n?1)Fp of the previous frame, and an interpolation operation section for generating interpolation compensation data by performing an interpolation operation for the compensation data which is read from the conversion table according to the insignificant bits of the image data of the current frame and of the post driving status data of the previous frame. And the conversion table further comprises a singular point conversion table used when the post driving status data of the previous frame is a first data. These tables are selected depending on whether the post driving status data of the previous frame is the first data or not.

  • Patent number: 6667730
    Abstract: A display has a display panel of a first aspect ratio and is able to display on the display panel an image of a second aspect ratio whose width element is larger than that of the first aspect ratio. The display has a gate driver, a data driver, and a timing controller. The gate driver sequentially selects gate lines of the display panel. The data driver stores data for one gate line and supplies the data to one of the gate lines selected by the gate driver. The timing controller supplies control signals to the gate and data drivers so that predetermined data is displayed in top and bottom non-image areas of the display panel during a vertical blanking period. The display is capable of displaying images of different sizes.

  • Patent number: 5999158
    Abstract: A drive circuit for a display device including a display panel for displaying an image line by line has a data register. The data register is used to store optional data in response to a control signal, to overwrite the stored optional data with display data, and to prepare display data for a given line of the display panel. The data prepared in the data register is transferred to the display panel to display the given line of the display panel. The drive circuit is capable of supplementing display data if the display data is improper for the display, thereby securing the quality of the displayed images.
